A DESCRIPTION OF THE REQUEST :
JFileChooser/WindowsFileChooserUI doesn't support Windows's new file chooser design (since Windows Vista).

JFileChooser looks like this: http://i.stack.imgur.com/oMQKN.png
But the native file file chooser on Windows 7 looks like this: http://i.stack.imgur.com/lNOWC.png

The main difference is the navigation tree on the left instead of the places bar and the address bar on the top instead of the combobox.

JUSTIFICATION :
A WinXP-style file chooser looks ugly in Windows Vista, 7, 8, or 10 environment. Windows Vista has released 9 years ago and Java still has the old file chooser, even if Windows XP is not supported by Java.
